CAR-VENTI LATO R.

SPECIFICATION forming part of Letters Patent No. 536,885, dated April 2, 1895.

Application filed April 2, 1892- Serial No. 427,520. (No model.) I

To all whom it may concern.-

Be it known that I, MARTIN D. MUGAN, of the city of St. Louis, in the State of Missouri,

have invented a certain new and useful Improvement in Oar-Ventilators, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

This ventilator is composed of porous fabric with means of dampening the same, the said fabric being stretched across orifices in the walls of the car so that the dust and cinders are arrested and pure air enters the car.

My invention also includes means for carrying an inward current of air through the fabric and certain details set forth in the claims.

Figure I is a longitudinal section of part of a passenger car showing the inner wall in elevation with parts broken out. Fig. II is an inside elevation of the apparatus with adjacent parts of the car, portions being in section. Fig. III is a vertical transverse section taken at III-III, Fig. II. Fig. IV is a vertical transverse section taken at IV-IV, Fig. II. Fig. V is an enlarged detail section taken at IVIV, Fig. II. Fig. VI is a section taken at VIVI, Fig. V.- Figs. VII and VIII are outside elevations showing modifications. Fig. IX is a horizontal section taken at IX-'-IX, Fig. VII. Fig. X isa horizontal section taken at X-X, Fig. VIII. Fig. XI is an inside view of the door as shown in Fig. VII. Fig. XII is an enlarged detail horizontal section taken at IXIX, Fig. VII. Fig. XIII is an enlarged detail showing the sliding member of the hinge in its extended position.

1 is the wall of a passenger car.

2 are the windows and 3 the parts of the car wall or side between the windows. The parts of the wall 3 have orifices. Each orifice has sides 4 and top and bottom 5 and 6.

7 is a panel having an air orifice 8.

9 is an outside door or doors that may be used to close the orifice upon the outside or to act as a deflector to force the air through the ventilator into the car. To this end the door is connected by one of its vertical edges to the car body 3 by hinges.

10 is a spring, one part of which is attached to the car body 3 and the other part (11) of which bears against the inner side of the door,

or vice versa so as to push the door open. The door has closing cords 12 connected to its inner side and passing under rollers 13 to a drum 14. on which they are wound. The drum shaft 15 has a turn-knob 16 within the car by means of which the cords may be wound up to close the door or unwound to allow the door to open, under the influence of the spring 10. The shaft 15 carries a spur wheel or notched disk 17 whose teeth engage a fixed stud 18 to prevent the turning of the drum when in its normal position, as shown in Fig. V.

19 is a spring bearing against the opposite end of the drum from the knob and holding it in its normal position.

When it is desired to turn the drum the knob is pushed inward which relieves the wheel 17 from engagement with the stud and the drum may then be turned.

In Figs. III and IV the doors are connected to the car by hinges at one edge and in this case the doors may have the hinges alternately upon the right and left edge so that one set may be used when the car is running in one direction and the other set when the car is running in the opposite direction; or if desired the doors may all be set open in which case the air would enterand escape from each ventilator alternately. The doors may be opened to an angle of thirty degrees more or less with the side of the car so as to deflect the air inward through the ventilator. If but a very small amount of air is needed the door may be almost closed and may be opened to increase the amount of air deflected.

In Figs. VII, IX, XI, XII and XIII the dooris shown h'aving hinges at both edges, the door being detachable and to this end the pintle part 20 of the hinge is fast to the door and the eye part 21 secured to the car body, the pintle 20 being turned down. These parts of the hinge may be reversed if desired in which case the pintle would be turned upward, so that the eye might be lifted from it in detaching the door. The object of this construction is to render the door effectual whichever end of the car is in the lead; the rear hinges alone being used. In order to prevent the hinges at the free edge of the door from interfering with its closing the eye pieces 21 are made to slide in a strap 22 from their active position seen in Figs. XII and .XIII to an inactive position indicated by dotted lines in Fig. XII, and shown at the right side in Fig. IX. In this construction the spring 11 is made removable, one part being held by a strap 23 of which there is one near each edge of the door (at the inner side). In putting the door in condition for use the spring is fixed at the edge of the door that will be at the rear and that edge of the door hinged to the car. This is done by the trainmen while the car is standing.

In Figs. VIII and X there are folding doors hinged at their outer edges to the car body and supplied with separate cords 12 so that either of them may be used the other one be ing in closed position.

I will now describe the preferred manner of supporting the porous fabric which is stretched across the ventilator aperture. This may consist of wire gauze or textile material 24 supported in a frame so that it may be readily removed for cleansing or renewal. The frame has a narrow bottom-bar 25 connecting the lower ends of the side bars 26, the side bars being connected near their upper ends by a bar27 whose top is formed with two inclined surfaces 27 whose purpose is to deflect to each side, jets of water projected upon it from a pipe 28 above. Thus the fabric 24 may be saturated when desired. The upper ends of the side-boards 26 may fit the part 28 of the water pipe. see Figs. II and III, and be held in place by it, while the bottom-bar 25 fits in the recesses of springs or cleats 29 at each side of the recess. The frame may be removed either from the inside or outside of the car after opening the shutter 7 or the door 9.

30 is a drip trough receiving any superfinous water dripping from the lower end of the orifice. This drip-trough discharges into a waste-pipe 31 that is carried to the bottom or end of the car.

32 is a water pipe connected with an elevated water tank or some water supply under pressure, and extending from end to end of the car.

33 are branch pipes connecting the main pipe 32 to the jet pipes 28. These jet pipes extend over the bar 27 its whole length and have in the under side a number of jet holes 28 for the water jets that impinge upon the top of the bar 27.

34: is a valve in each branch pipe to close the same and to give means for opening it to supply water to the jets. Thehand wheel of the valve is within the car so that the ventilator cloth may be saturated at any time. It is preferred that the ventilator aperture should have a shield 35 of wire-work at the outer and inner side, as seen in Fig. III.

I claim as new and of my invention- 1. In a car ventilator, the combination witha car provided with openings in its side wall out of connection with the car windows, frames located in said openings, separated sheets of porous material stretched across said frame, a water supply pipe ending and discharging between said sheets of porous material, and a deflector between said sheets for directing water to said porous material, substantially as and for the purpose set forth.

2. The combination, with the hinged deflector of a car ventilator of a spring forcing the deflector outward, a. cord attached to the deflector, a winding drum for the cord and a knob within the car upon the shaft of the drum, substantially as set forth.

3. The described combination, in a car ventilator, of the air orifice in the wall of the car, a deflector hinged at the side of the orifice, a spring forcing the deflector outward, a cord adapted to pull the deflector inward, a winding drum for the cord having endwise movement, an operating knob of the drum, a spring pushing the drum endwise into its normal position, acog wheel on the drum shaft and a stud engaging with the cog wheel when the drum is in its normal position, substantially as set forth.
